For Otto Porter, it’s two seasons and done for the Georgetown forward. Porter made his announcement at a 3 p.m. ET news conference.

Porter, who averaged 16.2 points and 7.5 rebounds per game, was the Big East’s player of the year and led the Hoyas to a share of the Big East regular season title. His scoring average in conference play was 18.1 points per game.

Porter's breakout performance—the one that put him on everybody's radar—came on the road against Big East rival Syracuse on Feb. 23. Porter produced 33 points, eight rebounds, five steals and hit five 3-pointers while playing all 40 minutes in a Hoyas victory.

"The toughest part was knowing you're going to leave a great place like this," Porter said. "I love this place."

Georgetown’s season ended abruptly when it was upset in the round of 64 of the NCAA Tournament by No. 15 seed Florida Gulf Coast.

DraftExpress.com has Porter ranked as a lottery pick, going No. 8 overall to the Oklahoma City Thunder, which acquired that pick as a result of sending James Harden to Houston.

"Whatever they ask him to do, he's going to be able to do," Thompson said.
